Instructional enzyme model



FIG. 1 is a front elevational view of an instructional enzyme model shown in an open position showing my new design.

FIG. 2 is a front elevational view of the instructional enzyme model of FIG. 1 shown in a closed position.

FIG. 3 is another front elevational view of the instructional enzyme model of FIG. 1.

FIG. 4 is a left side elevational view of the instructional enzyme model of FIG. 1.

FIG. 5 is an enlarged right side elevational view of the instructional enzyme model of FIG. 1, with substrates removed; and,

FIG. 6 is a perspective view of the instructional enzyme model of FIG. 1 with substrates removed.

The broken lines showing environmental structure in the form of substrates bound to the enzyme in FIGS. 1-3 form no part of the claimed design. 

CLAIM I claim the ornamental design for an instructional enzyme model, as shown and described.
